Well the input function is being called before the validator function ever gets a chance to act. The validator function receives an already-formed isbn13 datum. Is there an is_valid() which takes text input? Perhaps there should be -- though I think it would have to be isbn_is_valid() or something like that. -- Gregory Stark EnterpriseDB http://www.enterprisedb.com Ask me about EnterpriseDB's RemoteDBA services! -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
